Description

  The present invention relates to a personal computer input device for a handicapped person that allows a person with a physical disability to perform an input operation using a remaining function, and more particularly to a configuration of a pointing device.

  Conventionally, various personal computer input devices for persons with disabilities have been proposed in which the configuration of the pointing device is devised in accordance with the site and degree of disability in order to enable the use of personal computers by physically handicapped persons.

  Among them, as a personal computer input device for a handicapped person for a user who has a particularly high degree of disability and a severe disability such that only the head can be moved slightly, as shown in FIGS. The display 101 connected to the personal computer main body 100, the pointer 104 attached to the user's head via the fixture 103, the controller 105 installed on the display 101, and one end set at the user's mouth A switch provided with a switch operating tube 106 has been proposed. The pointer 104 includes a pneumatically operated switch 104a that is operated by the expiratory pressure and / or inspiratory pressure applied to the tube 106, a CPU 104b, a light receiving unit 104c for infrared rays emitted from the controller 105, and a signal processing unit. 104d, an oscillation unit 104e, a modulation unit 104f, a light emitting unit 104g that emits infrared rays toward the controller 105, and a power supply unit 104h that supplies power to each unit of the apparatus. The controller 105 includes a CPU 105a. A light receiving unit 105b for infrared rays emitted from the pointer 104, a signal processing unit 105c, an oscillation unit 105d, a modulation unit 105e, and a light emitting unit 105f for emitting infrared rays toward the pointer 104. It has been.

  This disabled personal computer input device controls the mouse cursor 101a displayed on the display 101 in the following procedure. That is, infrared light is emitted from the light emitting unit 105 f of the controller 105, and the infrared light is received by the light receiving unit 104 c of the pointer 104. The CPU 104b of the pointer 104 calculates the horizontal and vertical inclination angles of the pointer 104 with respect to the controller 105 from the amount of light received by the light receiving unit 104c, and the calculated data from the light emitting unit 104g together with the on / off state data of the pneumatically operated switch 104a. The emitted infrared rays are transmitted to the light receiving unit 105b of the controller 105. The CPU 105a of the controller 105 obtains the coordinate value of the pointer 104 on the display 101 based on the transmission data from the pointer 104, and transmits this coordinate value data to the personal computer main body 100 via the serial interface. The personal computer main body 100 controls the display position of the mouse cursor displayed on the display 101 based on the coordinate value transmitted from the controller 105.

  On the other hand, the pneumatically operated switch 104a provided on the pointer 104 activates the mouse cursor when the user blows into the tube 106, and clicks, double-clicks, cancels, drags and locks when exhalation or inspiration is applied. Perform each action.

  Therefore, by combining the movement of the pointer 104 and the exhalation or inspiration applied to the tube 106, a pointing operation similar to that using a mouse, a trackball, or the like can be performed (for example, see Non-Patent Document 1).

The personal computer input device for a handicapped person according to this publicly known example allows the use of a personal computer only by adding exhalation or inspiration to the tube 106 while operating the pointer 104 within a limited angle range. By attaching the pointer 104 to the head and setting one end of the tube 106 at the mouth, it is possible to use a personal computer by a user who has a severe obstacle such that only the head can be moved slightly. In addition, since data is wirelessly transmitted and received between the pointer 104 and the controller 105, the user's behavior is less restricted than in the wired system, and the user's daily life is less likely to occur.
